After scoring his first Arsenal goal of the season in the 2-1 victory at Marseilles on Wednesday night, Theo Walcott has promised there will be a lot more to come in this campaign.

The 24-year-old's sweetly struck volley opened the scoring at the Stade Velodrome, after he capitalised on an error from Marseilles defender Jeremy Morel. The England international is now back on the right-wing after a brief spell down the middle, and finished last season as Arsenal’s top scorer in all competitions with 21 goals.

"The cross came in and the full back missed it," Walcott told arsenal.com. "It felt like the ball was in the air for a decade and I managed to keep my eye on it and [it was] pure technique into the top corner.

"It meant a lot getting off the mark [for the season]. Hopefully there are going to be more to come now. I started pretty late last year and I finished as top goalscorer so it's a good sign. I'm pretty sure of that."

Walcott was proud as the Gunners extended their away winning record to 10 matches, but has challenged the club to show the same level of performance at the Emirates Stadium.

"It just shows how consistent we are away from home," he said. "We just need to be a bit more consistent at home now, that's the next big step. If we show that, we can really go far this season. I really believe that."

2013/14 - 1 goal

2012/13 - 3

2011/12 - 3

2010/11 - 6
